“I am inclined to believe Warren Tucker – particularly since the paper notes he discussed it with Phil Goff – and Tucker has always struck me as a pretty straightforward person, but it is unlike Phil to get caught like this. He is usually so precise,” Mr Dunn said.

In a question Mr Dunne described as the “toughest” of the day, MHD asked who he would vote for if he had to choose between New Zealand First leader Winston Peters and Act leader Don Brash.

“Assuming abstention was not an option, it would be a reluctant vote for Brash.”

Mr Dunne followed the live chat with a tweet where he stated he had never denied smoking pot, and that unlike Clitnon, he did inhale.
